UNITED STATES PATENT OF ICE.

CHARLES W. HUNT, OF NEW YORK,

ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 297,934, dated April 29, 1884-,

Application filed March 15, 1884. (No model.)

To all whom it may concern:

Be it known that 1,0. W. HUNT, a citizen of the United States, residing at New York, in the county and Stateof New York, have invented certain new and useful Improvements in Elevator-Buckets, of which the'following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 represents a section of an elevator or hoisting bucket with my improvements attached. Fig. 2 is a rear view of my improved caster.

My invention relates to improvements in buckets for elevating or hoisting coal, grain,

or other material; and it consists in the novel.

arrangement and combination of devices, as will be hereinafter more fully set forth, and specifically pointed out in the claims.

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

Referring to the drawings, A represents an elevator-bucket constructed of sheet iron or steel, of any desired size and form, and has the usual handle or bail, which is pivotally secured to the bucket in the usual manner. The bucket is also provided on itsbottom with the small rollers generally used in devices of this kind for the purpose of assisting in moving the bucket from place to place. It has also been customary to place on the rear and near the bottom of the bucket another wheel, which has generally been secured between projecting flanges or other means whereby this wheel has been held rigidly to the frame, and only permitted to travel in a direction similar to that in which the bucketis drawn.

For obvious reasons the construction just referredto has proved objectionable.

I will now proceed to describe my improvement, which I find by experiment removes the objections referred to.

B represents a hollow casting, having a curved portion, B', conf0rrning to the shape of the lower rear end of an elevator-bucket.

.The curved portion B forms projections 1), ex-

tending out from the main portion of the hollow casting, and has holes 12 b b, adapted to receive the rivets by which it is securedto the bucket. A perforation, b isformed in the side of the casting B, through which is passed a set-screw, b for the purpose herein- I in conjunction with the set-screw b permits of a free revolving motion to the caster-wheel. The lower portion of the stem is bifurcated to form flanges d d, in which is journaled a shaft,

d having mounted thereon a wheel, E. I At a point, e, the stem is enlarged to form an offset or shoulder, upon which the lower portion of the hollow casting B rests, as shown in Fig. 1.

From the foregoing description it will be seen that if the bucket be filled with coal, grain, or other material, and the same be drawn toward the place where it is desired to deposit the material, the rear wheel having a free revolving motion, by reason of its being swiveled, as before stated, the strain upon this wheelis very much lessened, and the bucket can be turned in any direction without doing any injury to the wheel.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The elevator-bucket A and hollow casting B, having projections b, in combination with the stem D, provided with a groove, D, and flanges b b, the wheel E, and set-screws b, all constructed to operate substantially as and for the purpose set forth.

2. The elevator-bucket A, constructed as herein shown and described, in combination with the swiveled wheel E, substantially as and for the purpose set forth.
